Abstract (en)
[origin: US6190308B1] An endoscopic video system for correcting a video image of an object to be studied has a processing unit controlling an electronic image recorder which has a multiplicity of image elements, each generating an output signal upon illuminating a known test object. The processing unit has a learning mode of operation, wherein it determines and records a correction value corresponding to a difference between an output signal of the known test object and a generated one by each of the image elements, and a recording mode, wherein an output signal generated by each image element upon illuminating an object to be studied is adjusted at the correction value.
